The interface name already is org.bluez.Characteristic so we really
need Characteristic again.

Why you don't return an error? Signals are not that great here, you
also want to track the caller so that if it exit you cancel the
operation.

Same here, signals are useful for async events not for response, also
you are mixing terminology of set/get with read/write, either use one
or the other.
